Hi
[This is Dovecot 2.3.1 at FreeBSD STABLE-11.1 running in two jails at distinct
servers.]
I did upgrade from 2.2.35 to 2.3.1 today, and I do become pounded by error
messages at server1 (and vice versa at server2) as follows:
| Apr 2 17:12:18 <mail.err> server1.lan dovecot: doveadm: Error:
dsync(server2.lan): I/O has stalled, \
no activity for 600 seconds (last sent=mail_change, last
recv=mail_change (EOL))
| Apr 2 17:12:18 <mail.err> server1.lan dovecot: doveadm: Error:
Timeout during state=sync_mails \
(send=changes recv=mail_requests)
[…]
| Apr 2 18:59:03 <mail.err> server1.lan dovecot: doveadm: Error:
dsync(server2.lan): I/O has stalled, \
no activity for 600 seconds (last sent=mail, last recv=mail
(EOL))
| Apr 2 18:59:03 <mail.err> server1.lan dovecot: doveadm: Error:
Timeout during state=sync_mails \
(send=mails recv=recv_last_common)
I cannot see in my personal account any missing replications, *but* I haven't
tested this thoroughly enough. I do have customers being serviced at these
productive servers, *thus* I'm back to 2.2.35 until I do understand or have
learned what is going on.
Any ideas/feedback?
FYI: I haven't seen such errors before. Replication has been working for years
now, without any glitches at all.
Regards,
Michael
